318 exhaust manifold bolts and nuts....

Thanks for the tips, but I don't have access to heat or a welder. Just me myself and I. Hmmm... Is there any way to re thread a stud? I'll keep trying, but it doesn't look good right now. Is the thread pattern on the outside of the stud 5/16x24?


a cheap propane type solder torch and some nut buster should work, but if you do break it, you can always use a heli coil repair kit ( ive used them on head exhaust holes before with no issues ).
